ENH: Zenodo integration?

[KCollins]

Please consider syncing this repository on Zenodo using Github integration: https://help.zenodo.org/docs/profile/linking-accounts/
That way, each release (as well as the most recent version at any given time) will be citable with an associated DOI.
A zenodo.json file can also be used to automatically populate Zenodo's metadata fields.

Also, please consider:

• Adding a CITATION.cff file to the GitHub repository
• Adding a zenodo.json file (like this one: https://github.com/KCollins/conjugate_map/blob/main/.zenodo.json) to encode metadata for Zenodo integration
